LOCOlVlOTIVE WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 619,303, dated February14, 1899. Application iiled March 22, 1897. Renewed September 22, 1898.-Serial No.` 691,618. (No model.)

To all whom t may concern:

Be it known that we, NORMAN L. HAYDEN andANDREw WILDMAN, citizens of theUnited States of America, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inLocomotive Vater-Puriiers, of which the following is a specification.

Our invention relates to certain improvements in a device for purifyingwater for use in steam-boilers, said improvements being designedespecially for use upon locomotiveboilers.

The object of the invention is to devise an apparatus which shalleffectually cleanse the water of all injurious ingredients, as well asof all dirt and sediment before it reaches the boiler, and to do this ina vessel of such a nature as to be easily accessible and readilycleaned.

To such end the invention consists in certain novel features embodied inthe apparatus described in detail below, the essential portions of whichwill be definitely pointed out in the appended claim.

The preferred form of our invention is illustrated in the drawingspresented herewith, in which- Figure l is a side elevation ofthe entireapparatus, showing in vertical diametrical section the vessel which isintended to receive and collect the dirt and impurities; and Fig. 2 is ahorizontal section in line 2 2 of Fig. 1.

Referring to the drawings, A is a steam-pipe leading from the boiler. Bis a suction-pipe leading from the water-supply. C is an injectorconnected to both of said pipes.

D is the discharge -pipe of the injector, which leads therefrom to avessel E, in which the impurities are to be collected. Fis a pipeleading from said vessel E to the boiler.

G is a pipe connecting the pipe D with the pipe F and designed to cutout the vessel E when necessary.

H is a blow-off pipe intended for use in cleaning out the vessel E.

The steam-pipe and the suction-pipe are provided, respectively, withvalves a b. The

pipe D is provided with a check-valve CZ and a gate-valve d. The pipeGis provided with a gate-valve g. The pipe F is provided with acheck-valve f, and the pipe H is provided with a valve h, adapted toclose the same.

The vessel E is divided into an upper and a lower chamber by a partitione, inade up of perforated disks e e2, between which is a loose filteringsubstance e3. The top of the vessel is covered by a cap e4, which may beremoved, and the disks e e2 are held between brackets e5 c e7 e8. Eachof the disks is provided With notches e9 to enable them to pass by thebrackets and with pivoted buttons e to slip beneath the brackets andsecure the disk in place. Beneath each of the disks is a reticulatedfabric, preferably cloth, cl2. The pipe D at the point where it entersthe vessel E has a slight bend cl2, which is turned laterally andupwardly to direct the water against the cloth and in a directionsubstantially tangentialwith the wall of the vessel, so as to cause asort of whirlpool and assist in keeping the cloth free from sedimentthat might clog it up.

The operation of the device is as follows: The steam is turned on withthe valves b d open. As the steam enters the injector it draws the waterfrom the pipe B and delivers the same at a boiling temperature throughthe pipe D, past the check-valve d, and into the vessel E. The boilingof the water prepares it to deposit the greater portion of 'itsimpurities which collect in the bottom of 'the vessel E. As the lowerportion of this vessel fills the purer water at the top is forced upwardthrough the cloth @12, the filtering substance e3, the second cloth, andinto the top of the vessel, from whence it passes on through thecheck-valve f to the boiler. The two thicknesses of cloth cl2 and theinterposed filtering material thoroughly remove Whatever sediment mightotherwise fail to settle in the bottom of the vessel E. As the bottoniof the latter iills up the valve hin the blow-od pipe is opened fromtime to time, discharging the sediment and impurities collected. At muchgreater intervals the top e4 of the vessel is removed, the disks takenout, and the cloth or other reticulated fabric and interposed filteringmaterial removed and renewed. This may all be done without interferingwith the feeding of the boiler, because of the auxiliary pipe G, whichfurnishes IOO an independent connection between 'the injector andtheboiler and enables the purifying vessel to be cut out entirely forcleaning.

We claim as new and desire to secure by Letters Patent- In a device forpurifying water for boilers, the combination with a cylindrical vesselhaving a filtering partition perpendicular to the axis of the vessel,cfy a boiler feeder adapted to deliver water to said vessel at a boilingtemperature, a pipe leading from said feeder into said vessel on oneside 'of said partition and discharging the Water into said vessel in asubstantially tangential direction and toward said partition, and a pipeleading 15 our hands, at Chicago, in the county of Cook zo and State ofIllinois, this 19th day of March, 1897.
